RIDA · Range Indexed Data Access

Indexed datasets.
Read one field.

Build a static dataset from JSON, then retrieve the stored value your application needs, from disk or through an ordinary HTTP byte-range request.

How it works

How a field is retrieved

Turn JSON records into a data file and an index. Keep the data on disk, object storage, or a CDN.

Use a record ID and a top-level field name. The index locates that stored value without a full dataset download.

The reader decodes the selected value. HTTP hosting must support 206 Partial Content responses.

Where RIDA fits

Use RIDA for catalogues, translations, help centres, directories, and reference archives that are prepared ahead of time and read repeatedly.

Use a database for live writes, transactions, joins, and dynamic queries. A project can use both for different parts of its data.
